You can download it from nvidia here: http://www.nvidia.com/content/DriverDownload-March2009/confirmation.php?url=/Windows/9.14.0702/PhysX...
If that link eventually expires, google nvidia PhysX download, it'll likely be the top result.
Although this problem is fixable, it's still inexcusable that as customers we have to work out the problems ourselves, although I understand it's impossible to know every single bug, when discovered EA should have fixed this problem.
It seams that although installing the above fixes it, it only works when launching through origin. If you launch it through steam as a non-steam game, it gets the same error (at least it does for me). It's not a major issue, but being able to have games all in one place would be nice.
I have been having same error message but I looked in the C:\Program Files\Origin Games\Dragon Age\__Installer\physx\redist folder and there is no physx install file there or is there one on my laptop and the game plays on it. I was wanting to play the game on my desktop but the copy method to my desktop gives the the invalid license error. Everything else seems to be the same on both but game still does not play.
there was no file in my with physx in the _install does the game need to launch first or?
Again, you need the latest PhysX - http://www.nvidia.com/object/physx-9.16.0318-driver.html
That is the right version, not the one provided by ItsBilbo and others.
If you're reading this at some later date, go to http://www.nvidia.com/Download/index.aspx and click on the 'NVIDIA PhysX System Software' link to download the latest version, or try http://www.nvidia.com/object/physx_system_software.html
Ok after fidelling around the file folders i came to an solution.
Go to Program Files (in my case program files x86) > Origin Games > Dragon Age > __installer > physx > redist
there you should see and Phys-x install file, install it, after that the game should work.
OK but for those of us not using NVIDIA graphics the game doesn't install physx. yet we get the error and physex wont install unless you have an NVIDIA gpu. SO is there a way to tell the game you don;t need physx?
Whether you're using Intel, AMD or Nvidia graphics, you need the PhysX software. See above for the download link.
For non-Nvidia cards this is just a software implementation of PhysX which runs off the CPU rather than the GPU like with Nvidia cards.
